STORING AND MAINTENANCE
Soiled air filters reduce the engine output by restricting air to the carburetor. If the air contains a lot of dust,
the air filter should be checked more frequently.
WARNING! Never run the engine without the air filter element installed.
1. Press tabs at the top of the air filter cover and tilt away from the engine to remove the cover.
2. Remove the filter cartridge.
3. To loosen debris, gently tap the filter cartridge on a hard surface. If the filter cartridge is excessively dirty,
replace with a new one.
Note: Never clean the air filter cartridge with gas or inflammable solvents.
Clean the air filter cartridge only with compressed air or by tapping it.
4. Install the filter cartridge.
5. Close the cover and secure it properly by snapping tabs back into the correct slots at the top.
CHECK AND ADD THE ENGINE OIL
The Briggs & Stratton 675EXi engine on this lawn mower is made with a special feature Check & Add(TM).
The oil never needs to be changed. Before each use check the oil level and add additional oil if the level is
not within the Min - Lax levels.
REPLACING THE BLADE
For safety reasons you should only ever have your blade sharpened, balanced and mounted by an
authorized service workshop. For optimum results, it is recommended that the blade be inspected once a
year.
WARNING! Before you remove the grass collection bag, stop the engine and wait until the blade
stops completely.
WARNING! You will need garden gloves (not provided) and a wrench (not provided) to remove the
blade.
NOTE! Don't invert the mower. Tip it slightly towards the oil filler pipe and reach under the deck.
WARNING! Always handle the blade with care; sharp edges could cause injury. USE GLOVES.
Replace your metal blade after 50 hours mowing or 2 years, whichever is sooner, regardless of
condition.
WARNING! If the blade is cracked or damaged, replace it with a new one.
WARNING! Don't hold the blade by hand directly.
NOTE! Maintain the sharpness of the blade when cutting grass. If the blade has worn excessively
and become pitted and blunt, it should be replaced or sharpened. The sharpness of the blade will
affect the performance of the lawn mower.

STORING AND MAINTENANCE
For safety reasons we recommend that the blade only be changed by someone qualified and authorized to
do so.
Hold the blade and unscrew the blade bolt counter-clockwise using a wrench. Remove the washer and the
blade.
Fit a new blade or re-sharpen the blade. Place the blade on the two studs on the blade flange and then
replace the washer and bolts. Make sure the blade is correctly located, and then firmly tighten the bolt. Do
not over tighten. The up turn of the blade must project into the motor compartment.

2. Ensure the grass bag is empty.
3. Clean all debris from under the mower deck.
4. Store the lawn mower on a flat and level surface with the mower upright.
5. Store in a safe place which is not accessible by children or people who are not familiar with the lawn
mower's operation.
STORING THE LAWN MOWER FOR EXTENDED PERIODS
If the lawn mower is to be placed into storage for more than 15 days, storage maintenance must be
performed on the lawn mower. If the following steps are not carried out, when you next operate the
lawnmower it may not start correctly and may need to be serviced.
CAUTION! Do not empty the gas tank in enclosed areas, near fire or when smoking. Gas fumes can
cause explosions and fire.
1. Empty the gas tank with a gas suction pump if available.
2. Start the engine and let it run until any remaining gas has been used up.
3. Clean the cooling fins of the cylinder and the housing.
